To reduce energy consumption, so-called replacement fuels (‘EBS’) are increasingly being used in the cement industry. A good and efficient starting point, which, however, is accompanied by corrosion problems. Hydrochloric acids are released to a considerable extent during the combustion of biofuel during cement production. In addition, it comes to condensation of chlorine or hydrochloric acid. Their diffusions lead to harmful acid formations, which attack the anchor and steel surfaces. The same applies to the flue gas scrubbing. Here too, acids in combination with high operating temperatures lead to corrosive deposits at the sensitive points of the installation. GBT addresses these extremely aggressive influences with coating systems developed specifically for the interests of the cement industry.
